Warner has debuted a new poster for Noam Murro's upcoming 300: Rise of an Empire. The movies first trailer will launch online tomorrow at 4:30 PM PT / 7:30 PM ET. Based on Frank Miller's latest graphic novel Xerxes & told in the breathtaking visual style of the blockbuster 300, this new chapter of the epic saga takes the action to a fresh battlefield on the sea as Greek general Themistokles [Sullivan Stapleton] attempts to unite all of Greece by leading the charge that will change the course of the war. 300: Rise of an Empire pits Themistokles against the massive invading Persian forces led by mortal-turned-god Xerxes [Rodrigo Santoro] Artemesia [Eva Green], vengeful commander of the Persian navy.
